"A friend of our's referred us to Mark when we were shopping to replace our old HVAC system. We found Mark to be very professional and he did a great job with installing a new HVAC system for our home. He priced a Goodman HVAC system that came to be much cheaper than other providers we contacted at the time. It's been almost a year since and we have had zero problems with the system. I would definitely recommend Mark to my friends and family.""Working with Mark has been a breath of fresh air, because he is very responsive, honest and doesn't try to upsell you anything. I wish all contractors were like Mark!"
"Mark Olis HV/AC delivered exactly what we needed. Our new AC/heat pump systems were installed expertly by Mark. We highly and strongly recommend Mark as he gets the job done very very well and at an affordable and reasonable price. Mark works very hard, sticks with it till the job is done by when he said it would be done, keeps you informed along the way, and makes very sure you are comfortable with using the new systems. He came back a week after installation just to check with us to see how everything was working and always responds quickly to any call or email we send him if/when we have questions about the systems. We appreciated Mark's no nonsense, get the job done approach and caring that we understood how to use our new AC/heat pump systems. We work with Mark to regularly service our AC. We are enjoying greater comfort in our everyday living year-round because of his fine work. Money well spent with Mark Olis HV/AC."
